IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part of Letters Patent No. 201,346, dated March19, 1878; application filed May 31, 1877'.

To all whom it may concern:

Be it known that I, ALBERT S. HOYT, of Winona, in the county of Winonaand State of Minnesota,'have invented certain new and usefulImprovements in Grain-Binders; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same.

This invention is in the nature of a mechanism for securing the cord orwire used to bind gavels of grain. v

The invention consists in cord or wire nippers or holding-jaws, operatedso as to twist together the ends of the cord or wire after said cord orwire has been passed around the gavel, and so as to impart to suchtwisted portion a kink, whereby the cord or wire is securely fastenedaround the gavel.

In the drawings, Figure 1 is a top-plan view of my apparatus; Fig. 2, afront end view of the same; Fig. 3, a side elevation; Fig. 4, a

. longitudinal sectional elevation on line mm,

Fig. 1 Fig. 5, a transverse section on line y 4 Fig. 1; Fig. 6, a sideelevation, showing the necessary modification of the drivingwheel toadapt the mechanism for tying wire; Fig. 7, an elevation of a gavel withthe cord twisted but not kinked; and Fig. 8 shows the :cord asvkinked,so as to secure it around the gavel.

In a mechanism where the cord is not tied in a knot, to secure it arounda gavel,,it is necessary that the cord .should be of a glutinouscharacter, so that when its ends are brought side by side and twistedtogether they shall adhere to one another; but this alone is notsufiicient to unite such ends so firmly as to resist the strain uponthem from the gavel.

'I' therefore,' after twisting the ends of such glutinous or stickycord, kink them or press them down upon the gavel, and, being separatedfrom the body of the cord, the twist and the downward pressure willserve to cause such ends to double up or be kinked, and; thereby thecord will be firmly secured around; the gavel. This is fully illustratedin Figs. 7

and 8. Such cord may be prepared withpitch or other sticky or glutinoussubstance.

The mechanism herein shown for bindinggavels of grain consists of adriving-wheel, A, suitably connected with the drivingpower of theharvester to which the binder is attached, part of whose periphery ispro- .vided with cogs, more or less in number, according as cord or wireis to be used. This wheel has upon one face an incline or camlikeprojection, B, semicircular in form, and serving to operate anelbow-lever, E, which is provided at its outer end with a fork, F.

G is a shaft placed within a hollow shaft, H, and rotating with saidshaft H, but having an independent longitudinal sliding movement withinsaid shaft imparted to it by means of the vibration of the lever E, thelevers fork F engaging with'a pin, a, projecting from said shaft Gthrough a slot in shaft H, and thus forming the connection between'shaftGrand lever E.

On the shaft H is a pinion, I, which meshes with a gear, J, on acounter-shaft, L, and there is also upon this counter-shaft a pinion, K,which meshes with the large wheel A. By this system of gearing motion istransmitted from the wheel A to the shaft H, or v vice versa, accordingto the location of the power.

Over the shaft H, at one end, is placed a sleeve, e, and this sleeve isconnected with the shaft G by a pin, e, passing through a slot in theshaft H, whereby said'sleeve rotates with the shaft H and has alongitudinal movement with the shaft Gr.

Fixed upon this sleeve 0 are nippers M, consisting of a fixed jaw, b,and a movable jaw, b. The jaw b is provided with a spring, d, the powerof which is exerted to draw said jaw from the jaw b.

The face of the jaw b is armed with teeth 0, or is otherwise maderoughor frictional, so as to readily and securely hold cord or wire placedbetween it and the jaw b.

p The nippers are inclosed by a separable or partible tubular casing, N,one member, N, of which is hinged at f, and has a tailpiece, g. Thetail-piece g of the part N is connected with a rod, 0, which is providedwith frictionrollers h, that engage with a projecting rim or cam, P, onthe wheel A, whereby said rod receives an intermittent reciprocatingmovement.

R is a pair of shears for severing the cord or wire. One of the bladesof these shears is movable, and is actuated by a rod, S, that isintermittingly operated by contact with projections (l D on the wheel A.

T is a stop on the shaft L, operating, in connection with the rim U onwheel A, to stop the revolution of the gearing when the gear A has runout of pinion K.

My improved binder being constructed substantially as above described,its operation is as follows: The wheel A is caused to revolve until itsteeth mesh with pinion K but just prior to the meshing of wheel A andpinion K the projection D on the wheel A will strike againstthe rod S,and so move it as to cause the shears to cut or close. At the same timethe cam P will operate the rod 0, pressing it forward, and therebyclosing the movable member N of the partible casing, which causes thejaws of the nippers to come together-that is to say, themovement of themovable'member .L of the casing is imparted to the-moving jaw b of thenippers, and'as said jaw is closed it grasps and firmly holds the end ofthe cords after they have been passed around the gavel.

The rotation of the wheel A causes itscam or incline B to so act uponthe lever E as that said lever moves the shaft G horizontally in thedirection of the arrow, Fig. 5, while at the same time the gearingrevolves the shaft H. The nippers receive the rotary movement of thegearing, and by the horizontal movement of the shaft G they are movedcorrespondingly through the casing. This combined horizontal and rotarymotion of the nippers serves to twist the ends of the cord together thelength of the travel of the nippers, in order to secure the cord aroundthe gavel.

When the wheel A has completed about a half-revolution relatively to thenumber of its cogs, the projection 0 will actuate the rod ll, so as toopen the shears, and thus have then in readiness to sever the cord atthe propel time.

,When the cogs of wheel A shall just have 7 run out of pinion K, thelever E will have been freed from the incline B and the rod 0 will havebeen freed from the rim P. A spring, W, will then act upon the lever Eto force its forked end outward, whereby the shaft G will be retracted,carrying with it the nippers M, and the mechanism will then be ready forthe next gavel.

' It will be understood that the cord is passed around the gavel, andthen severed, and then grasped in the nippers, and as they are made totravel in the direction of the arrow in Fig.

5, the cord is twisted; and when the nippers have traveled the length oftheir casing the nippers continue to revolve without advancing, and thecord is thereby kinked, and is finally released by the opening of themovable jaw, and twisted up close to the gavel.

The freeing of the rod 0 from the rim P serves to release the member Nof the easing, and the spring 01 is at liberty to act upon the jaw b ofthe nippers and force it away from jaw b, thereby releasing the cord.

As soon as the teeth of the wheel A are freed from the pinion K the facet of the stop T comes in contact with the face of the flange or rim U onthe wheel A, and said stop being keyed to the counter-shaft L, themotion of the machine is stopped, with the exception of the wheel A,which continues to re volve, so as tobe ready to begin the nextmovement.

The wheel A may be removed when it is desired to tie or bind with iron,and the wheel shown in Fig. 6 be substituted therefor, the

difference between the two lying in the number of cogs and thecorresponding and necessary location and arrangement of the rim, cams,and projections. I

By removing the pivot of the lever E, the machinery may be used inbinding with wire instead of cord, and without kinking the wire. In thiscase the Wheel A may be used instead of that shown in Fig. 6. I

Having thus fully described my invention, what Iclaim as new, and desireto secure by Letters Patent, is' a 1.
